Burden of the NPC

Every gamer knows the feeling of dread: the mission objective shifts, and suddenly you are forced to protect a fragile, excruciatingly slow non-player character (NPC) as they wander blindly through a warzone. The "escort mission" is universally despised, yet developers have continued to force them into blockbuster games for decades.
The Burden of the NPC explores the profound disconnect between ambitious game design and the stark limitations of artificial intelligence. Creating a companion that acts autonomously without ruining the players agency is a programming nightmare. To prevent the NPC from solving the puzzle for the player, designers must artificially lobotomize them, reducing their walking speed and eliminating their survival instincts, which turns an engaging adventure into a tedious babysitting job.
This book dives into the complex math of pathfinding algorithms and navmeshes. It charts the evolution of the escort mission from infuriating retro cliches to modern triumphs like The Last of Us, explaining how developers finally learned to hide the invisible strings.
